Welcome to Down On The Street, where we admire old vehicles parked on the streets of the Island That Rust Forgot: Alameda, California. When did the Suburban make the switch from "bouncy truck" to "edge sprawl commuter?" Not by 1972!
Aside from the wheels and maybe a paint job a couple decades back, this Suburban seems quite original. No Deliverance-style lift kit, no winch, no window tinting. Just a big two-wheel-drive steel box, suitable for hauling six drywallers and all their gear to the work site in totally adequate comfort, with nothing much to break down.
The good ol' 350! Sure, given how often small-block Chevy motors get swapped around, this truck might have a 305 or 400 by now, but chances are pretty good the original engine still lives under the hood.
